Hi there.Ive loved Xcom for a while now but at this time its become sorta a drag. I played it in and out and I really have no use for it any more and while it was really fun for a stratagy game I think its time to say good bye. Worse yet is that I cant even play it at school for some reason. SO Im here asking.... any one wana trade this 30$ game for a 10 dollar game?

Note:this is also going to be my first tiem trading a game so I really dont know how it works.
